I am stuck with quesiton . I add the machine IP in /etc/hosts " IP inlanefreight.htb" when i am doing nsloookup i am getting error "** server can’t find 82.202.129.10.in-addr.arpa: NXDOMAIN " . What’s the reason ?

Can you show the full nslookup command you used? also is this on windows or linux?

I think the reason for this error is that the DNS record for “inlanefreight.htb” only exists in a particular nameserver. So consider using command like: dig @nameserver_ip inlanefreight.htb

Let suppose this is the IP 10.129.184.1 and the domain is inlanefreight.htb. I add this in the /etc/hosts file " 10.129.184.1 inlanefreight.htb" . Now the question this find FQDN of this inlanefreight.htb. so I used the command ‘nslookup 10.129.184.1’ and i am getting this error Server: 192.168.1.1
Address: 192.168.1.1#53

** server can’t find 82.202.129.10.in-addr.arpa: NXDOMAIN

I’m stuck as well. I’ve tried it with and without adding the ip/domain to /etc/hosts. It would be helpful if HTB displayed how many characters and/or in what format they are looking for like THM does. I’ve tried nslookup, dig, wafw00f, and even nmap, none of the results are the correct answer (even with a “.” at the end and/or the full path name of “https://www.” and/or any variation thereof with/without the full path name):

a. root . servers . net

nstld . verisign-grs . com

root . inlanefreight . htb

inlanefreight . htb

x. x .x .x. in-addr .arpa

The only good outcome of trying to answer this question was stumbling upon Flag No. 1 for the next section, question 1. I’m not sure if I’m over thinking something, glossing over something obvious to others, entering the correct answer but not adding some required character, or that I’m totally lost. I hope this information helps others get further than I did, and if so, please advise without giving the answer away.

sk7698277’s nslookup command above worked for me. As far as the connection timed out, it seems that the servers are offline. Try respawning the target machine. It’s been awhile since I did this one. Which module is this for?
